NGC7635 - Bubble Nebula

Info

The Bubble Nebula is one of my favourite objects in the night sky. A Emission nebula in Cassiopeia, the shape of this object is caused by the stellar wind from a massive hot Wolf-Rayet star. The star itself is 40 times the size of our sun and is reponsible for a stellar wind moving at 2000 kilometers per second. The rest of the red glow is from a cloud of gas surrounding the bubble itself. The Bubble Nebula is 7100 light-years from Earth and the bubble part is 6 light years in diameter.

I've reprocessed this again using a tip found here



I've reprocessed this one based upon some advice to try and make it less 'salmon pink' - I think it's worked quite well!
